No token available

Error message

No token available

What it means

ExportButton reads the auth token from presentation metadata (`presentation.metadata.Token`). If it is null or undefined the export cannot authenticate against the export service, so 'No token available' is thrown before any fetch is made. It indicates the user's session/token was not injected into the client metadata.

Solutions

1. Ensure the user is logged in and the token metadata is set before rendering the export button.
2. Check that the presentation/auth plugin providing metadata.Token is properly installed and initialized.
3. Re-authenticate (refresh session) if the token was dropped after expiry, then retry the export.

Example fix

// before
const token = getMetadata(presentation.metadata.Token)
if (token == null) throw new Error('No token available')
// after
const token = getMetadata(presentation.metadata.Token)
if (token == null) {
  ui.notify('Please sign in again to export')
  void login()
  return
}

const token = getMetadata(presentation.metadata.Token)
if (token == null || token === '') { ui.notify('Sign in to export'); return }

function hasToken(t: string | null | undefined): t is string { return typeof t === 'string' && t.length > 0 }

try {
  await handleExport()
} catch (e) {
  if (e instanceof Error && e.message === 'No token available') {
    ui.notify('Your session has no auth token; please sign in again')
  } else throw e
}

When it happens

Trigger: `getMetadata(presentation.metadata.Token)` returns null because the login/session flow did not provide a token, or the plugin metadata was not registered/initialized.

Common situations: Expired or missing session, running the component in a context without login metadata (tests, storybook, embedded preview), or misconfigured auth plugin registration.
